Which case established the need for law enforcement to read Miranda rights upon detention?

The case that established the need for law enforcement to read Miranda rights upon detention is Miranda v. Arizona. This landmark Supreme Court decision, issued in 1966, addressed the rights of individuals in police custody and the necessity for law enforcement to inform suspects of their rights before interrogation.

The ruling emphasized that individuals must be aware of their Fifth Amendment rights against self-incrimination and their Sixth Amendment right to counsel when they are subject to custodial interrogation. The Supreme Court determined that the failure to inform suspects of these rights could lead to the inadmissibility of any statements made during interrogation, as it could violate their constitutional protections.

Miranda v. Arizona fundamentally shaped police procedure and reinforced the principle that individuals should be aware of their rights to ensure fair treatment under the law. This case is often cited as a key moment in establishing the procedures that police must follow to protect the rights of suspects in custody.
